銑(xian)(xian)削(xue)(xue)(xue)動(dong)(dong)力(li)頭一般與機(ji)械、滑臺配套使用，常用于對鑄件、鋼及有(you)色金屬零件的(de)銑(xian)(xian)平面或銑(xian)(xian)槽加工(gong)。銑(xian)(xian)削(xue)(xue)(xue)動(dong)(dong)力(li)頭的(de)好壞決(jue)定(ding)著銑(xian)(xian)削(xue)(xue)(xue)工(gong)件的(de)質(zhi)量，首先要看銑(xian)(xian)削(xue)(xue)(xue)動(dong)(dong)力(li)頭的(de)轉速是否(fou)穩定(ding)，如果你買了(le)劣質(zhi)的(de)銑(xian)(xian)削(xue)(xue)(xue)動(dong)(dong)力(li)頭，那么(me)轉速的(de)不均(jun)(jun)勻，機(ji)床在(zai)銑(xian)(xian)削(xue)(xue)(xue)中(zhong)產生震動(dong)(dong)，進而(er)導致加工(gong)件銑(xian)(xian)削(xue)(xue)(xue)不均(jun)(jun)勻。

銑削動力頭的操(cao)作(zuo)技(ji)術對(dui)工(gong)(gong)件的質量(liang)好(hao)壞(huai)也有著決定性(xing)的意義(yi)，銑削動力頭切削深度可以等(deng)于加(jia)(jia)工(gong)(gong)余量(liang)，即(ji)一次(ci)銑去(qu)全部的加(jia)(jia)工(gong)(gong)余量(liang)。

例：銑(xian)(xian)(xian)削動力(li)頭(tou)銑(xian)(xian)(xian)削鋼料時，t＝3—5毫米(mi)(mi)；銑(xian)(xian)(xian)削鑄(zhu)(zhu)鋼或鑄(zhu)(zhu)鐵時，t＝5—7毫米(mi)(mi)。當(dang)工(gong)件表(biao)面要求租糙度為(wei)精(jing)(jing)(jing)一鍛(duan)時，可分(fen)粗銑(xian)(xian)(xian)及半(ban)精(jing)(jing)(jing)銑(xian)(xian)(xian)兩步銑(xian)(xian)(xian)削。粗銑(xian)(xian)(xian)留0．5—1.0毫米(mi)(mi)余量(liang)，由半(ban)精(jing)(jing)(jing)銑(xian)(xian)(xian)切除。當(dang)工(gong)件表(biao)面要求粗糙度為(wei)浮一留時，可分(fen)粗銑(xian)(xian)(xian)、半(ban)精(jing)(jing)(jing)銑(xian)(xian)(xian)及精(jing)(jing)(jing)銑(xian)(xian)(xian)三(san)步銑(xian)(xian)(xian)削。半(ban)精(jing)(jing)(jing)銑(xian)(xian)(xian)t＝1．5—2．0毫米(mi)(mi)(2次(ci))；精(jing)(jing)(jing)銑(xian)(xian)(xian)t；0．5毫米(mi)(mi)左右(you)。
